I read Hitler's Willing Executioners when it was published.
Although I agreed with his thrust, I had three reservations at the time, and
now: First, others far better traced the roots of German and European
anti-Semitism; Second, he failed to examine the political mechanics by which
this anti-Semitism was transformed into widespread, complicit action in
Germany, and not elsewhere; Third, he is too black-and-white, not recognizing
anything in between, and thus undermined his case before other academics and
many in the public (not everyone is a hero, which does not make them
complicit, but as he says also does not justify later denial of knowing if
they did. Many who commit an evil learn not to repeat doing that
evil).

It is very important to a society to publicly recognize evil, and to hold
forth the ideals of positive action. It is AS important that the
populace be taught in word and deed how to act against evil, and to practice
that. In America and elsewhere in the West, we've done a nice job of the
former but, especially in Europe and much of America — almost half the
electorate — a poor job of the latter.
